growisofs writes unreadable dvd+rw
Hi,
I'm trying to backup a system using dar + growisofs.
I have two files of 2Go-2k that I try to write to a dvd+rw.
growisofs seems to do it well, but I cannot mount the dvd to check it.
Any pointer ? I already read everything I found :/
(debian sid, kernel 2.6.8)
# growisofs -dvd-compat -R -J -Z /dev/hdc $1/$file1 $1/$file2
